2.2.7 Center-of-gravity detection (probe recognition mode)
This method finds the contour of the component and recognizes the component from the
center-of-gravity position and tilt of the main axis. This is utilized for recognizing
irregular shaped components.
The center-of-gravity and main axis tilt are found from the contour (edge) only. So there
is no effect on the center-of-gravity position and on main axis tilt even when there is a
hole in the component.
This method utilizes 2 recognition modes, "Center-of-gravity detection" and "Melf chip
recognition".
n
NOTE
The square and circles do not have an axis so the tilt is undefined.
